Recent directional changes on some downtown streets have readers wondering about the legality of crossing double lines in the street and the possibility of restriping the roads to make things more clear to motorists.

Reader Guy Morgan wrote: "Dear Doc, Second Street is now a two-way street with a double yellow line between Third and Fourth Avenues N. The double yellow line means 'do not cross.' How does someone driving north cross the double yellow line and enter into the gated community at Fourth Avenue N or drive south on Second Street cross over the double yellow line and make a left into the parking lot just south of Fourth Avenue N?"

We passed Morgan's concerns on to Mike Frederick, the city's manager of neighborhood transportation, and we also asked if more conversions were in the works. Frederick told us that the city plans to convert First Street between Central and Fifth Avenue N from a one-way to a two-way operation.

He also said work on Second Street and the conversion of First Street had been delayed during the World Series.

Although the roads are marked with a double solid center line, which indicates that passing is prohibited, this doesn't not restrict a driver from passing over the center line to access a driveway on the opposite side of the road, so Morgan shouldn't worry about being ticketed.

Work on Fifth Ave. S

Beginning Monday, two Fifth Avenue S intersections will close for about a month to make way for a $1.3-million drainage improvement project designed to control street flooding.

Fifth Avenue S at 20th Street S and at 22nd Street S will be closed to traffic from Monday through Dec. 3.

Fifth Avenue S will be accessible to local traffic between 28th Street S and 16th Street S during the closures, with through traffic diverted to First Avenue N and First Avenue S. Through traffic on 22nd Street S will be diverted to 24th Street S. City engineers say that local access will be maintained along 22nd Street from Fourth Avenue S to Seventh Avenue S.
